I'm trying to open videos to work on coding in Datavyu and I finally got it to allow me to actually download the files (before I was getting the error message saying the Quicktime Java Libraries were not found), but now once I open the file it says that the track timing information could not be calculated. I have tried two different forms of the video files too, including .mov and .mpg. I'm not sure what I should try to fix the error other than perhaps uninstalling then reinstalling the quicktime player.

I'm using QuickTime 7, the latest edition. The QuickTime player doesn't seem to be working either though and states to install the Apple Application Support, instead my videos have been playing on the VLC media player. I figure it could be due to having to only upload a certain aspect of QuickTime in order to be able to get the Datavyu program to recognize the java libraries.

Datavyu's uses QuickTime to play its videos. If your videos do not play externally in Quicktime, then they will unfortunately not play in Datavyu. The playback issues should not be due to the custom download but you can check to see if your videos run smoothly with the standard download of Quicktime.

What to include in your posted question:

How support works:

Search to see if someone has already asked your question.

Found someone who has already asked your question? Use the thumb button to up vote the question to make it easier for the next person to find.

Can't find anyone who has asked your question? Create a new question by pressing the 'ask a question' button in the top right. Put in as much detail as you can. Include a sample file if possible and any scripting details.

Help others! Can answer somebodies question, or is the existing answers out of date or just wrong? Create a new answer and put in as much detail as you can, including step by step instructions.

Has someone answered a question you asked? Use the tick answer next to the answer to mark it as correct. This makes it easier for other people to find the answers to similar problems.

Don't create answers thanking people. Use voting and ticks to thank people instead. This increases their 'reputation' or 'karma' (the number next to your name when you sign in). It also makes helpful questions and answers much easier for other people to find.
